Natural gas. Energy determinationWhat is ISO 15112 about? ISO 15112 provides the means for energy determination of natural gas by measurement or by calculation and describes the related techniques and measures that are necessary to take. The calculation of thermal energy is based on the separate measurement of the quantity, either by mass or by volume, of gas transferred and its measured or calculated calorific value. The general means of calculating uncertainties are also given. ISO

the wet-cup method has been adopted as the reference method

The significant changes made in EN 12697-3:2013+A1:2018 compared to EN 12697-3:2013 are:

OHSAS 18002 does not create additional requirements to those specified in OHSAS 18001 nor does it prescribe mandatory approaches to the implementation of OHSAS 18001

Subsequent parts of ISO 11138 provide additional specific requirements for biological indicators for defined sterilization processes
